Ken,
Dyno's can vary depending on software version, type of dyno etc etc. The dyno sheet they Jim's put up reflects rear wheel numbers. I would have John Golden dyno tune it. Depending on your pipe though you may or may not be able to get both cylinders tuned independently and this is important. I forget which pipe and which throttlebody you have, but these can also affect your numbers as well. I know a few people with the 120 that use D&D Performance Baffle, and 54mm Zippers as was suggested by Jim's at the time. Those people were seeing numbers a in the 120's as Jim's suggests in their dyno and these were done on DynoJet 250i dynos. Ken if you are in the end happy with it, great, you asked if it was good or bad I just made the suggestion to check with Jim's because you may be leaving quite a bit of power on the table again depending on your total config.
The power is hard to get away from once you have it on the bagger
Ride a stock one and you will feel like your on a moped.
Maybe i'm not happy. I asked the dealer about the stock throttle body before we installed this engine. He claims it's big enough, and all I need. I also was under the impression it was 54 mm. Evidently I was wrong. Here's a copy of the email I got back from Jim's. :
Hello Ken,
Thank you for your support of JIMS. Yes, you will want to run something a little bigger to get that motor running at its full potential. Go with a 54mm-55mm unit, all the big players in the industry offer something in that range (Zippers, HP Inc, etc). A free flowing air cleaner in general is recommended (a "cone style" usually flows best). If your filter has the cone exposed, I would stick with that one. After that, make sure you have some good flowing 2 into 1 pipes, and you have the air system completed. Please feel free to respond to this if you need any more recommendations. Again, thank you for your support of JIMS.
With that said Harry, I think you're right. hoist been telling me the same thing. I need to change throttle bodies I think. I'm basically happy with the bike, but, it still feels like it's smothered or something. Like,,it wants to do more. I'll keep you guys posted what's happening. Re-Tune again it looks like!
Thanks Harry.
